Effect of Dexmedetomidine on Emergence Agitation in Children With or Without Tube Insertion Under General Anesthesia
The Effect of Intramuscular Dexmedetomidine on Emergence Agitation in Children Undergoing With or Without Tube Insertion Under General Anesthesia
The investigators are inviting your child to participate in this research study because your child is having myringotomy (putting a tiny incision in the eardrum with or without tube insertion) under general anesthesia.
The purpose of this study is to determine whether a single injection of Dexmedetomidine (study medication) decreases the frequency of awaking from anesthesia frightened or agitated in children having myringotomy surgery as compared to those children who receive placebo (sterile saltwater).
Study Overview
Detailed Description
Emergence agitation (EA) is common in children, especially in the preschool age group who undergo general anesthesia. It has been described as a mental disturbance during the recovery from general anesthesia and can consist of hallucinations, delusions and confusion in the child. To the parent or caregivers this may be seen as moaning, restlessness, involuntary physical activity & thrashing about in bed. Emergence agitation (EA) can result in the child losing their intravenous therapy (IV) access & bodily injury. Some agitated children may retain vivid memories about their negative experience waking up from anesthesia. This can result in seeing new behaviors by the child such as anxiety, nighttime crying and temper tantrums. Dexmedetomidine given as an injection into the muscle of children is considered investigational, which means it hasn't been approved by the U.S. FDA for treatment of this problem in children.
Immediately following surgery measurements of eye contact, purposeful actions, aware of surroundings, restless and crying are observed and recorded using the Pediatric Anesthesia Emergence Delirium (PAED) scale in PACU.
Follow-up is made approximately 3 days after surgery by phone call or/and email with parent(s) to see if child has experienced any of the following: sleep disturbances, anxiety, eating disturbances, postoperative muscle pain or swelling at the injection site.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Dexmedetomidine
Single injection of Dexmedetomidine (study medication) compared to receiving Placebo in Myringotomy surgery decreases emergence agitation.
|
Active study agent: Dexmedetomidine at 1 microgram/kilogram Intramuscular (IM) Placebo study agent: Same volume as the study drug of placebo (normal saline). All blinding, labeling, preparation, storage of agents done by the pharmacist. The drug will be administered into the deltoid muscle by using a TB syringe attached to a 3/4 inch length and 25 Gauge width needle by anesthesia provider after the induction of general anesthesia by the anesthesia provider.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Participant's Severity of Emergent Agitation (EA) Using the Pediatric Anesthesia Emergence Delirium (PAED) Scale in PACU (Post-Op Area).
Time Frame: Participants will be followed for the duration of first PACU recovery step, an expected average visit of 30 minutes. Measurements will be observed immediately following subject's awakening from anesthesia.
|
The aim/measurement of the study is to determine whether or not a single IM injection of Dexmedetomidine will reduce the severity of Emergent Agitation (EA) in children undergoing Bilateral Myringotomy with/without tubes under general anesthesia. We used the only validated scale to assess the severity of post operative emergence delirium in pediatrics. This Pediatric Anesthesia Emergence Delirium (PAED) scale is a composite score of the following items:
Items 1, 2, and 3 are reversed scored as follows: 4-not at all, 3-a little, 2-quite a bit, 1-very much, 0-extremely. Items 4 and 5 are scored as follows: 0-not at all, 1-a little, 2-quite a bit, 3-very much, 4-extremely. The total score will range from 0 to 20; with 0 indicating no emergence delirium and 20 indicating extreme emergence delirium. |
Participants will be followed for the duration of first PACU recovery step, an expected average visit of 30 minutes. Measurements will be observed immediately following subject's awakening from anesthesia.

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Duration of Stay in PACU
Time Frame: Participants will be followed immediately following surgery, approximately 30 minutes. Measurements will be observed immediately following subject's awakening from anesthesia.
|
Duration of stay in the PACU (Post-Op Area) until discharge criteria are met based on modified PADSS score: level of consciousness, physical activity, hemodynamic stability, respiratory stability, oxygen saturation status, post-operative pain, and post-operative emetic symptoms.
Duration of time will be measured in total minutes participate is in PACU until discharged.
|
Participants will be followed immediately following surgery, approximately 30 minutes. Measurements will be observed immediately following subject's awakening from anesthesia.
